The encode process just seems to hang. I've attacted a file that exhibits all behavior - as you can see from the earlier logs, an identically-compiled/configured ffmpeg 2.8.7 has the same behavior on the same input. Thanks for any help, and sorry for the earlier. capture.ts <https://drive.google.com/file/d/0B4fu8KZMt9qnek9oeFFWaUszX0k/view?usp=drive_web> Weirdly, if I switch to using the spanish audio stream with exactly the same invocation, I can encode successfully: Is it possible the audio from the english stream is too corrupted to deal with? If so, since it plays back okay, is there any way that I can pre-process it so that libvorbis or ffmpeg's ac3 can play nicely with it? *Successful Logs* *Invocation* bin/hdhomerun_config 10391104 save /tuner0 - | /home/sam/bin/ffmpeg -i - *-map i:0x31 *-pix_fmt yuv420p -c:v libvpx-vp9 -s 640x360 -keyint_min 60 -g 60 -speed 6 -tile-columns 4 -frame-parallel 1 -threads 8 -static-thresh 0 -max-intra-rate 300 -deadline realtime -lag-in-fr ames 0 -error-resilient 1 -b:v 1000k -f webm_chunk -header /var/www/html/webm_live/tuner_720.hdr -chunk_start_index 1 /var/www/html/webm_live/tuner_720_%d.chk *-map i:0x35* -c:a libvorbis -b:a 128k -af 'pan=stereo|c0=FL|c1=FR' -f webm_chunk -audio_chunk_duration 2000 -hea der /var/www/html/webm_live/tuner_128.hdr -chunk_start_index 1 /var/www/html/webm_live/tuner_128_%d.chk *Successful Output (just trust me that it's working okay - the input is in bad shape but I can't figure out how to capture the logs in a way that's gmail-readable)* ffmpeg version N-81210-gfd4eb56 Copyright (c) 2000-2016 the FFmpeg developers built with gcc 4.8.3 (GCC) 20140911 (Red Hat 4.8.3-7) configuration: --prefix=/home/sam/ffmpeg_build --extra-cflags=-I/home/sam/ffmpeg_build/include --extra-ldflags=-L/home/sam/ffmpeg_build/lib --bindir=/home/sam/bin --pkg-config-flags=--static --enable-gpl --enable-nonfree --enable-libfdk-aac --enable-libfreetype --enab le-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 libavutil 55. 28.100 / 55. 28.100 libavcodec 57. 51.100 / 57. 51.100 libavformat 57. 44.100 / 57. 44.100 libavdevice 57. 0.102 / 57. 0.102 libavfilter 6. 49.100 / 6. 49.100 libswscale 4. 1.100 / 4. 1.100 libswresample 2. 1.100 / 2. 1.100 libpostproc 54. 0.100 / 54. 0.100 [mpeg2video @ 0x34bb980] Invalid frame dimensions 0x0. ...
