#1636(undetermined:new): FRAPS Video Color Space

#1636: FRAPS Video Color Space -------------------------------------+------------------------------------- Reporter: DJX | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: FRAPS color | Blocked By: space dark white washed out | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- The color space that ffmpeg uses on FRAPS videos seems to be wrong or mishandled. First, running ffplay on a video (color space detected as yuvj420p), the output looks washed out (too white). Second, when transcoding a video to H264 (which keeps the color space as yuvj420p) the output looks too dark. Forcing the color space to yuv420p, the output looks fine. Third, when transcoding a video to MPEG2 (which changes the colorspace to yuv420p), the output looks fine. Here is how ffmpeg detects the original file: {{{ ffmpeg -i "C:\Fraps\Movies\cod2sp_s 2012-08-12 13-39-04-15.avi" ffmpeg version N-43418-g633b90c Copyright (c) 2000-2012 the FFmpeg developers built on Aug 9 2012 23:56:26 with gcc 4.7.1 (GCC) configuration: --enable-gpl --enable-version3 --disable-pthreads --enable-runt ime-cpudetect --enable-avisynth --enable-bzlib --enable-frei0r --enable- libass - -enable-libcelt --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-l ibfreetype --enable-libgsm --enable-libmp3lame --enable-libnut --enable- libopenj peg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable- libtheo ra --enable-libutvideo --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-li bvorbis --enable-libvpx --enable-libx264 --enable-libxavs --enable-libxvid --ena ble-zlib libavutil 51. 67.100 / 51. 67.100 libavcodec 54. 51.100 / 54. 51.100 libavformat 54. 22.104 / 54. 22.104 libavdevice 54. 2.100 / 54. 2.100 libavfilter 3. 7.100 / 3. 7.100 libswscale 2. 1.101 / 2. 1.101 libswresample 0. 15.100 / 0. 15.100 libpostproc 52. 0.100 / 52. 0.100 [avi @ 000000000217aa20] non-interleaved AVI Guessed Channel Layout for Input Stream #0.1 : stereo Input #0, avi, from 'C:\Fraps\Movies\orig.avi': Duration: 00:07:26.85, start: 0.000000, bitrate: 530091 kb/s Stream #0:0: Video: fraps (FPS1 / 0x31535046), yuvj420p, 1920x1080, 60 tbr, 60 tbn, 60 tbc Stream #0:1: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 48000 Hz, stereo, s16 , 1536 kb/s At least one output file must be specified }}} Let me know what other info you need.

#420(undetermined:new): Sound fragments after seeking

#420: Sound fragments after seeking --------------------------+-------------------------- Reporter: kaptnole | Type: defect Status: new | Priority: important Component: undetermined | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced: 1 Analyzed: 1 | --------------------------+-------------------------- While trying to use FFmpeg libs as a developer I found the following: When decoding sound from some compressed audio formats and doing a seek, the first decoded packet after seeking is buggy. I had this with some mp4 files with aac audio codec and some wmv files with wma audio codec. Looks like some leftovers from internal buffers - but I am using 'avcodec_flush_buffers'! That of course leads to nasty sound noise/clicks. See attached sourcecode. Basically it shows the first few bytes of the first decoded sound packet then seeks back and shows the first packets decoding again. If you use it with some wmv or mp4 file with sound you should see see effect that both outputs at 0 are different but should be equal. Just make sure the sound is not only silence at the first 10 packets. Or am I missing some other flush...whatever function here? I am developing under windows using the actual ffmpeg git version. Confirmed for 32 and 64 bit version, self compiled and downloaded autobuilds. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/420> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
