[issue460] support interlaced h264

Just curious, is there a definition what is a wish, and what is important? doc/issue_tracker.txt in ffmpeg svn If someone needs something to reencode the movie from his camcorder and it does not work, he may consider it important. true, but priority is from the point of view of the ffmpeg developers every user considers the issue he submitted important. Maybe wish is too low but important is certainly too high ... [...] and what is a bug? from issue_tracker.txt: An error, flaw, mistake, failure, or fault in FFmpeg or libav* that prevents it from behaving as intended. Every H.264 decoder has a set of features it claims to support we dont claim to support every feature thus our current guess is that the cause is that we plain dont support the video. I do not know this for certain yet as ive not investigated it yet ... If the picture is distorted, I consider this as a bug. You also get a distorted picture if you feed a word document into a h.264 decoder this doesnt make it a bug but rather unsupported input. Regarding this issue, is there any hope to solve this problem soon? If someone volunteers to work on it ... If you know C, the H.264 spec is public ffmpegs source is as well and we would certainly be happy if someone would send us a patch fixing this and other issues. But be warned, h.264 work is NOT fun at all, the spec is a obfuscated mess. -- priority: wish - normal __ FFmpeg issue tracker [EMAIL PROTECTED] https://roundup.mplayerhq.hu/roundup/ffmpeg/issue460 __

[issue412] Commit 11635 breaks MKV decoding

It seems to be due to generic ffmpeg conversion code behaving differently when having one added unknown stream that he just drop during the conversion. Maybe it still try to do some synchronization or some timestamps handling with the dropped stream ? Anyway, just adding those lines in any demuxer should be enough to trigger the bug in ffmpeg: st = av_new_stream(s, id); st-codec-codec_type = CODEC_TYPE_ATTACHMENT; with Index: libavformat/avidec.c === --- libavformat/avidec.c(revision 13251) +++ libavformat/avidec.c(working copy) @@ -608,6 +608,17 @@ if(avi-non_interleaved) clean_index(s); +st = av_new_stream(s, stream_index); +if (!st) +goto fail; + +ast = av_mallocz(sizeof(AVIStream)); +if (!ast) +goto fail; +st-priv_data = ast; +st-codec-codec_type = CODEC_TYPE_ATTACHMENT; + + return 0; } theres an attachment: ffmpeg -i in.avi test.avi ...
