RE: ffmpeg 1.1 (build 2013-02-09)

2 bugs: 1/ when aac is the output source, source tags are not copied

2/ when aac is input, ouput tags have issues with some non EN chars

Quid is it linked to any aac encoder or just libvo_aacenc

First let's test source is MP3

With:

ffmpeg -i withTagsMp3.mp3 -map_metadata 0 tagTestaacNoTagCopy.aac

no tag are copied, no warning or error

while both are OK:

ffmpeg -i withTagsMp3.mp3 -map_metadata 0 tagTestmp3OK.mp3

ffmpeg -i withTagsMp3.mp3 -map_metadata 0 -id3v2_version 3 tagTestID3v2mp3OK.mp3

Second let's test when source is AAC

ffmpeg -i withTagsAAC.aac -map_metadata 0 aac2mp3RUSSIAN_FAILS.mp3

Here French characters are copied, but Russian fails (note withTagsMp3.mp3 is OK with Russian) Returns an error:

"[aac @ 000000000222d3e0] channel element 2.0 is not allocated
Error while decoding stream #0:0: Error number -1 occurred"

ffmpeg -i withTagsAAC.aac -map_metadata 0 aac2aacFails.aac

Here no tags are copied at all !

"[aac @ 000000000222d3e0] channel element 2.0 is not allocated
Error while decoding stream #0:0: Error number -1 occurred"

For example the camera format is Video4Linux(v4l) and its name is "/dev/video0" in ubuntu,but what is it in MacOSX/iphone? The audio format is alsa(oss) and its name is "/dev/dsp" in ubuntu,but what is it in MacOSX/iphone?

It would be nice if SDL output could be done fullscreen. That would enhance the use of ffmpeg as a realtime video filter.

The unsharp filter gives much better results for sharpening videos than the smartblur and it would be useful if it had the same adaptiveness options like smartblur so that you can only filter the edges without amplifying noise.

Summary of the bug: Some related discussion was in ticket #1815.

When creating a Matroska / mkv file with FFmpeg with several subtitle streams all of them are marked as default and there seems to be no way to disable setting of the default flag for any of the subtitle streams.

Below is an example with the presumably correct metadata identifier default-flag=0 in use.

With both subtitles marked as default VLC shows the last subtitle stream but MPC-HC shows the first one (provided that no subtitle language preference has been set).

How to reproduce:

> ./ffmpeg -fflags +genpts -i test.mp4 -i test-en.srt -i test-fr.srt -c:a copy -c:v copy -c:s copy -metadata:s:s:0 language=eng -metadata:s:s:1 language=fra -metadata:s:s:1 default-flag=0 -map 0:0 -map 0:1 -map 1:0 -map 2:0 test.mkv

I checked it on 0.12 and current git versions. (with ffplay) avformat_open_input() returns error -1094995529 (AVERROR_INVALIDDATA FFERRTAG( 'I','N','D','A')) on this file VLC can open and play this.

Summary of the bug: How to reproduce:

Multiple definition errors when compiling for static build (haven't tried shared library). If this can't be made to work (since it is a problem with the libraries sharing the same code) then perhaps the configure script can detect the condition and advise to disable the conflicting options.

Hi, this is the swf screen-capture with audio generated by Jing.  https://dl.dropboxusercontent.com/u/89678527/2013-05-13_1157.swf

While this file could be played in Flashplayer, ffmpeg has problem in playing the video (image freezes), and audio playback is ok.

log shows:

Summary of the ticket:

add support to EXT-X-STREAM-INF and BANDWIDTH field in the generated M3U8 output.

Here is spec from  http://tools.ietf.org/html/draft-pantos-http-live-streaming-07

BANDWIDTH

The value is a decimal-integer of bits per second. It MUST be an upper bound of the overall bitrate of each media segment (calculated to include container overhead) that appears or will appear in the Playlist.

Every EXT-X-STREAM-INF tag MUST include the BANDWIDTH attribute

Here is command line:

C:\ffmpeg\ffmpeg.exe -re -i "rtmp://bar/foo.flv" -y -c:v copy -c:a copy -hls_time 6 -hls_list_size 5 -hls_wrap 30 -start_number 1 "C:\Tools\Foo\stream.m3u8"

Summary of the bug:

It'd be nice if the complex filter parser didn't bomb out with a cryptic error message when a user terminates their filter chains with a trailing ;.

How to reproduce:

% ffmpeg -i "$1" -i "$2" -i "$3" -i "$4" -filter_complex "
    [0:0] pad='max(240\,iw):max(180\,ih):0:0', scale='240:180', pad='480:180:0:0' [left_video];
    [1:0] pad='max(240\,iw):max(180\,ih):0:0', scale='240:180', pad='480:180:240:0' [right_video];
    [left_video] [right_video] overlay;
    
    ...

 http://thread.gmane.org/gmane.comp.video.ffmpeg.user/43173 The user provided a sample that plays fine with mplayer -demuxer mpegts, shows massive A/V desync with current ffmpeg, current ffplay and current mplayer -demuxer lavf. For ffplay this is a regression since 01d4619 (can only be tested by merging 4dece8c, crashes without), for ffmpeg this is a regression since 0ff4f0c. Until FFmpeg 0.10, -async 1 could be used as a work-around (the start of the output file contained dropouts but the rest of the output file played fine), this does not work since FFmpeg 0.11.

Ticket #823 is reproducible again for some samples, reported by ami_stuff: The 2bit and 4bit samples from ticket #823 are broken since 6184fa2, I will attach a PoC to show that this may not be related to the rawvideo decoder.

File is said to play fine with WMP12, plays (too small but) without artefacts with QuickTime?, shows many artefacts with FFmpeg.

Works mostly with ffmpeg -i noStartCode.mp4 -vcodec copy -bsf h264_mp4toannexb out.h264

(bug 299) I will attach a rv30 sample that continuously changes resolution between 354x288 and 256x208, plays fine with mplayer -vc rv3040. FFmpeg (and mplayer -vc ffrv30) mostly manages the first change from large to small (except that the first keyframe after the change is dropped), but ignores the changes from small to large, leading to massive corruption (and messages).

Given a small video stream:

./ffmpeg -f lavfi -i testsrc=d=5 -y loopme.mkv

And trying to loop it N times until the output reaches a given duration:

./ffmpeg -f lavfi -i movie=loopme.mkv:loop=0 -t 20 -y out.mkv

...leads to an infinite loop. All the frames >126 are dropped (the input has 125 frames):

I have tested i263 codec a bit more and found another issue.

Attached file was encoded with "deblocking filter" option enabled, (this is a normal video, not with pb-frames) and ffmpeg decodes it with visible artefacts.

Summary of the bug: When ffmpeg is instructed to do "-c copy" on input stream, it unexpectedly converts one of the input streams of type dvb_teletext into dvb_subtitle. More info can be found here:  http://ffmpeg.gusari.org/viewtopic.php?f=16&t=811&p=1527

How to reproduce: The original scenario, where the possible bug was discovered, used a command line like this:

ffmpeg -i udp://234.5.245.105:20000 -map 0 -codec copy -f mpegts stream.ts

Summary of the bug:

testsrc generates artifacts in the generated patterns, which appear as a discontinuity in the sliding colored band. How to reproduce:

ffplay -f lavfi testsrc=s=237x121
ffplay -f lavfi testsrc=s=237x119

This is most likely due to some rounding issue.

The file is playable so I believe the problem is minor. Still this flood should not happen, especially when the input is created with ffmpeg.

(issue 267) See  http://guru.multimedia.cx/small-tasks-for-ffmpeg/ for an explanation of the task.

Image range is currently only supported for format image2, not for iff images.

The index in asf files does not index all keyframes and is not very fine grained. Binary search should be used in addition to using the index so as to allow frame accurate seeking in asf. The inaccurate seeking issue can be seen in the seek regression test

hopefully this will make shorten files seekable in ffplay

Commit 39aafa5 added the -d option for ffmpeg:

commit 39aafa5ee90e10382e2f991e4d79d7852231df68
Author: Michael Niedermayer
Date:   Mon Apr 18 13:10:52 2011 +0200

    ffmpeg:Daemon mode, add -d as first option to try it.
    Signed-off-by: Michael Niedermayer

This option remains undocumented.

The would allow the fade color to be something other than the default of black. I am guessing it is currently possible in conjunction with the color filter, but I am unsure how. Example command:

# fade in first 30 frames of video with a color of red fade=in:0:30:red

Example docs:

color

Specify the color of the fade, it can be the name of a color (case insensitive match) or a 0xRRGGBB[AA] sequence.

The default value of color is "black".
